Calculate the pH and identify as acidic, basic,or neutral

Question

1. H= 1.10 * 10^-11 M
Answer: pH=11, basic
2. H= 2.61 * 10^-2 M
Answer: pH:1.58, acidic
3. OH= 4.0 * 10^-9 M
pH: 8.39, basic

Answer 1

For 1 the pH for (H^+) of 1.10E-11 is 10.95. I would not round that to 11.
2 is ok.
3 is not right. pOH is 8.39 which makes pH = 14-8.39 = ? and since pH < 7 it is acidic.
